From 24906b43b9bd9108aef17d18dfbb8764212085f7 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 28 Sep 1995 18:42:29 +0000 Subject: Thu Sep 28 13:05:54 1995 Roland McGrath Merge new message handling code from GNU gettext, by Drepper. * intl: New directory. * Makefile (subdirs): Add intl. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Return USER_ENTRY instead of storing it on our stack. * elf/rtld.c (rtld_command): Variable removed. (_dl_skip_args): New variable. (dl_main): Increment _dl_skip_args instead of setting rtld_command. If the link_map for the executable itself is not first in the chain, make it so. * sysdeps/i386/dl-machine.h (RTLD_START): Use _dl_skip_args as count of args to skip.
